AUTOMATIC CA R-BRAKE.

SPECIFICATION forming part of Letters Patent No. 274,767, dated March 27,, 1883. l Application filed January 22, 1883. (No model.)

To all whom it may concern Be it known that I, GUs'rAvos HErnEL, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful improvement in Automatic Gar-Brakes, of which the following is a full, clear, and exact descrip tion, reference being had to the accompanying of a car-body, and B the drawbar, connected to the bodyin the usual way, with a spring be hind it, so that it has a slight endwise movement.

O 0 represent the brake-bars suspended from beneath the car in the usual manner and pro vided with the brake-shoes. The brake-beam O is connected to a lever, D, at D, not far from one end of the lever, by a rod, 0 and the brake-beam U is connected to this same lever, D, at D close to theend, by a rod, (3 The other end of the lever D is connected by a rod, 0 to the outer end of a horizontal arm, E, on the lower end of a vertical rock-shaft, F, supported by hangers G G, secured to the timbers H, between which the draw-bar works, (see Fig. 5,) the shaft having a collar, 1, and

a pin, 1, as shown, which hold it from dropping out. Just above the collarI the rockshaft has rigidly secured to-it a disk, J, with pins J projecting upward from or near its periphery, as shown in Figs. 5 and 6.

K represents a plate (see Figs. 2, 3, 4c, 5, and

-6) pivoted by its outer end to the draw-bar,

side of the opening K is a notch, K facing outward, and on the other side is a notch, K

] facinginward. Now,it willbeunderstoodthat,

if the plate is forced to one side, as hereinafter described, until the notch K engages with 7 its pin on the disk J, and then the draw-bar forced back, carrying the plate K with it, the

shaft F will be rocked, thus operating the brakes; and, likewise, it will be understood that if the draw-bar is compressed, and then the plate moved in the other direction until the L represents a rock-shaft secured to the bottom of the car by suitable brackets, L and having its outer end turneddown, forming a crank, L, which is connected to the free end of'the plate K by a suitable rod, L Some distance from this end of the shaft it is provided with an arm, M, which is connected (See Fig. 5.)

by a rod, M, to the outer end of a crank, N

on a vertical shaft, N, journaled to the bottom of the car. A series of deflectors, O 0 0 (see Fig. 2,) having at their intersection a gate or valve, N,- which is capable of opening in either direction, as shown, according to the direction in which the train is moving, are se curedto the bottom of the car. When the train is standing still the gate is held closet by a spring, 0 (See Fig. 2.)

P are stop-pins to limit the opening of the gate.

The deflectors or air-chutes are made ofsheetiron, being closed at their backs to prevent side winds from having any effect on the gate.

The gate might be pivoted to the bottom of the car and the deflectors dispensed with; but I prefer to use them. i

The operation is as follows: Supposing the car to be going forward, the draw-bar would be in its outer position, as shown in Fig. 2, and the gate would be opened by the air, as shown, which would rock the shaft L pushing the free end of the plate K over until the notch K would be behindits pin on the disk J. Then, supposing the engine to be reversed, the draw lbar would be pushed in, applying the brakes, asdescribed, and, as soon as the train comes to a standstill and the draw-bar allowed to assume its natural position, the gate will be closed by the spring 0 and bring the plateK back parallel with the draw-bar, so as not to be engaged by either pin on the disk J. Now, supposing the car to be backed, the draw-bar will be pushed in, the gate opened forward by the air, and the bar or plate K pulled over by the rock-shaft L until the catch K is behind its pin on the disk J. Then, the engine being reversed, the draw-bar is pulled out, applying the brakes, as described, and when the train stops and the pressure is relieved from the draw-bar the valve or gate closes, operating the plate K, as already described.

I claim as my invention- 1. In a car-brake, a plate secured to the draw-bar by one end, and provided with notches at the other end for engaging with pins on a disk which is secured to a rock-shaft connected by suitable means with the brake-bars, in combination with a suitable-device for engaging the notches of the plate with the pins of the disk, whichever way the car is moving, substantially as shown and described.

2. In a car-brake, the combination of agate pivoted to the bottom of the car and adapted to be opened either way, according to the die rection in which the caris moving, a horizontal rock-shaft secured beneath the car, a plate se-r cured to the draw-bar by one end and provided with notches at the other end, and suitable means for connecting the horizontal rockshaft with said gate and plate, as set'forth.

3. A gate having a suitable spring to close it when the pressure is relieved from the drawbar, in combination with a horizontal rockshaft secured beneath the car, a plate secured to the draw-bar by one end and provided with notches at the other end, and suitable means for connecting the horizontal rock-shaft with said plate and gate, as set forth.

4. A gate pivoted to the bottom of the car and having a deflector or air-chute, in combination with a horizontal rock-shaft secured beneath the car, a plate secured to the draw-bar by one end and provided with notches at the other end, and suitable means for connecting the horizontal rock-shaft with said plate and gate, as set forth.
